This is a pack of four Serpent 1/10 EP Touring Car Wheels. These wheels are strong, yet lightweight, and feature extra ribs to help seat and support the foam inserts. The inner ribs tie into the hex adaptor providing extra stiffness and strength, while the outer rim edge helps to better support the tire. Plus, they are compatible with all 1/10 electric touring cars and weigh 11 grams each.
